Just pointing out: the statement `in India, the father's name is the child's last name' applies only to some parts of India. In other parts, names are more complicated so that one can get a name like Madhabhushi Venkata Narasimha Sesha Pundarikaksha Madhava Ravikumar (we used to call him A-Z though it does not literally contain all the letters), and on the other hand, some people may go by a simple name like Shubhranshu with no other part.
